Glee star Mark Salling may have gotten cozy with Audrina Patridge at Thursday's Us Weekly Hot Hollywood party at L.A.'s Voyeur -- but if the rest of Glee's cast are getting romantic, it's not with each other.

Amber Riley, who plays Mercedes on Fox's musical hit, insisted to that castmates Lea Michele and Cory Monteith are not an item -- despite flirtatious chemistry on the show and off-set rumors.

"No, no," she said at Thursday's party.

"We are like family," Riley explained. "It would be like incest. And that is just really gross."

Adds castmember Kevin McHale: "We haven’t had any scandals! We’re focused on what we’re doing."

McHale, who plays wheelchair-bound Artie, notes that the young ensemble cast doesn't have "any time" to get into trouble at Hollywood clubs or elsewhere. "We go over to each other’s houses -- we don’t really go out."
